ath11k: fix memory OOB access in qmi_decode
The decoded_size is wrongly assigned in ath11k_qmi_msg_handlers and it results
in out of boundary access in qmi_decode. The correct decoded_size should be
calculated from the related ind_msg structure.
This issue is exposed with QCA6390 because it needs 11 small memory chunks
which are stored in qmi_wlanfw_request_mem_ind_msg_v01 and hence the
decoded_size exceeds the wrongly assigend decoded_size.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2
